gas gauge still.....

Been working on this, not too hard obviously, for 4 years. Oh, it's a 93 auto 4.0. My gas gauge is always on E, now I know there's power at the gauge because the empty light is on. I finally got a donor fuel pump assembly. I removed the old one and sure enough a few checks with the dmm proved the old float assembly was not sending any signal. The donor was working fine so I swapped just the float assembly, because I put in a new fuel pump a few years ago. Once installed I rechecked the resistance and yes it was working like a charm. So back in it goes. Fire it up and nothing has changed!?! I would love any input. Has anyone gone through this? I did screw around with the gauge several times over the years, could I have blown something? Why would I have a empty tank light but no reading on the actual gauge? Please help.

I would check it with a different gauge to verify.. maybe pull the dash and check the connectors and see if they need to be cleaned at all.

There was a change in the gauge/sender, not sure of the year, but the resistance values were reversed, i.e., zero = empty, 88 ohm = full was turned around.

Search "fuel gauge", lots of info in other threads.

Not sure what a different gauge would accomplish, one float assembly showed resistance values the other didn't. I have searched fuel gauge threads for years with no luck.

May be a silly question but is the guage still on empty? If so is the tank empty?

Like Joe said some years more resistance meant fuller, other years emptier. Was the donor the same year?

You need to start by checking for voltage going in to the float assy at the fuel tank. The empty light is on. Is the tank really empty?
